Is overclocking the 570 safe?

[Enthusiast]

So I have a 570 with the Thermalright Shaman. It's quite awesome; on Arhkam City it stays below 50C.
The GPU, at least.

On my 5850 I could read my VRM temps on GPU-Z, but now I can't. I can't find a single application that will read my VRM temps, and it would definitely be dangerous to overclock without knowledge of my VRM's.
I've tried NVidia System Monitor, HWmonitor, GPU-Z, the whole lot.


Help?

Is there anything that could read my VRM temps?


or better,
Could I possibly proceed overclocking without knowing what they are?

Nope, not with the poor quality power vrm design and over all life span. High temps, large loads, and lack of cooling. They are made cheap with gtx 580 level power consumption. 4+2 power vrm phase design for the gtx 570 while the gtx580 is a 6+2 design. So that comes down to 4 phases for the gpu alone to handle 225W stock and much more when overclocked. The rest is just for the vram.
